[PATCH 04/23] drm/amd/display: Hook up DAC to bios_parser_encoder_control

["Timur Kristóf" <timur.kristof@gmail.com>]

Enable the codebase to use encoder_control()
when the encoder engine is one of the DACs.

The BIOS parser already supports calling the DAC1EncoderControl
function from the VBIOS, but it was not exposed anywhere.
